EmailThe concentric cable is used as electric service entrance from the power distribution network until the meter panel (especially where it is required to prevent “black” losses or electric power robbery), and as feeder cable from the meters panel until the panel or general distribution panel, just as it is specified in the National Electrical Code. This type of conductor can be used in dry and wet places, directly buried or outdoors. Its maximum temperature of operation is 90 ºC and its voltage of service for all the applications is 600V.
Benefits:
Especially suitable for connections single-phase from pre-assembled overhead lines low voltage, reducing the risk of theft of energy. Installation requires employment of aerial protections that are activated in the event short-circuit due to connection attempts clandestine, interrupting the feeding and exposing the attempted theft.
